Deep Tillage and Gypsum Response on Yield Attributes and Yield of Mustard (Brassica juncea)

In order to evaluate the response of deep tillage and gypsum application on yield attributes and yield of mustard a field experiment was conducted at Soil Research Farm of CCS Haryana Agricultural University, Hisar, Haryana, during the rabi season of 2000-01. The experiment was consisted of two tillage treatments i.e. conventional tillage (CT) comprising of one disc harrowing at 10 cm depth and one run of cultivator followed by planking and deep tillage with disc plough comprising 20-25 cm sub-soiling followed by CT and the gypsum treatments (control and gypsum @ 250 Kg/ha). The study clearly illustrates that a plough sole in a sandy loam soil can be alleviated by deep ploughing with disc plough and deep tillage & gypsum application increase stem & root diameter, fresh & dry weight, primary & secondary branches significantly. The grain yield of mustard can be increased by 26.41 % over conventional tillage and further increased by 32.07 % with the addition of gypsum.
